The use of renewable energy sources is on the rise. According to the U.S. Energy Information Administration, the world consumed 504.7 quadrillion Btu of energy in 2008 (the most recent year for which statistics are available). Ten percent of that consumption was from renewable energy sources, including biofuels, biomass, wind, and solar energy. By 2035, the EIA forecasts that consumption of renewable energy will account for roughly 14 percent of the total world energy consumption. World electricity generation from renewable fuels also figures to be on the rise. In 2008, electricity generation from renewable fuels accounted for nearly 19 percent of the world's total electricity generation, a figure the EIA estimates will be nearly 23 percent by 2035.
